How does ZelloWork differ from the free Zello app?


Zello Work Push-to-Talk (PTT) is a better option for businesses and organizations because it provides more control, more security, and assigned group channels. Zello Work offers the following features that are not available with the free app:

Zello Work Features


Private networks

A secure and private network with full control over who can access the network and which users communicate with each other within your network.

Secure end-to-end encryption

Zello Work offers encryption for all private and channel communications. The free Zello app only offers encryption for private messages as channels are public and anyone can listen. 

The following standards are used for both apps: RSA 1024-bit for authentication, digital signatures, secure media session keys exchange and AES 256-bit encryption for audio. TLS to control traffic encryption between Zello clients and Zello servers is also offered.

Dedicated servers

Zello Work operates on a physically separate network of servers that are specifically sized to meet the capacity needs of businesses. The free consumer Zello app, on occasion, may be affected by peak usage that can be unpredictable.

On-premise Server option

Host Zello Work on your own local WiFi or LAN network for ultimate control and privacy. The On-premise Server option is intended for clients who need maximum security, are located in remote areas with little to no internet connection, or have existing servers hosting all other software components.

Emergency Alert Button

A dedicated SOS alert button which sends audio, text, and location into a specified emergency channel. This is designed for businesses with lone-worker and hazardous environments. 

Management console

A web-based management interface to allow businesses to configure and control users, their devices, and channels. It also shows user status at-a-glance and has many account management features.

LMR integration

Zello Work includes support for a radio gateway solution that lets you seamlessly integrate your existing two-way radio network to Zello smartphones.

(Note: Both Zello Work and free Zello can be integrated with radio gateway solutions.)

Dispatch Hub

Select a dispatch channel and visualize a shared queue of incoming calls that you can respond to, replay, or discard. You’ll always know who messaged you when, and what’s next on your list.

Location tracking and Premium Maps

The Management Console offers a real-time mapping feature which displays a user's current location on OpenStreetMap, device battery level, and speed of travel. A Premium Map upgrade adds Google Maps and traffic services, along with Location History (bread-crumb trail).

Message Vault

A premium upgrade which allows you to archive all voice messages, photos, and texts for a period of up to 2 years. Data can be exported from the Management Console.

Clone User and User Import features

Use this handy feature to add new users and admins by cloning an existing record. Cloning can be done from a user's details screen or with the Import Users feature. 

User Roles

Allows administrators to choose who their users can hear and speak to within a channel. Driver and dispatch roles can be created, so drivers do not have to hear each other within a channel to reduce noise and distractions while driving. Broadcast channels can be created to make important announcements, without having everyone reply within the same channel.

The free app has roles available for channel management, including admins and moderators. 

Technical support

Our customers have 24/7 access to a dedicated technical support team.

Smart device and audio accessory support

The right devices and audio accessories empower Zello users to talk safely and clearly in loud environments. All accessories come with dedicated push-to-talk buttons and in some cases panic buttons.

Windows Mobile

We are compatible with Windows Mobile CE, as well as Windows Embedded Handheld devices, allowing companies to use existing mobile scanners as PTT devices.


Zello Work channels can link to other Zello Work channels that are not in the same organization or network. For example, your company's channel can link to a third-party or vendor's Zello Work channel.


With QuickConnect enabled, transmissions in channels can attain near-zero latency, comparable to the latency on a two-way radio. 

Developer Tools

Windows, iOS, and Android SDKs are available to simplify use between multiple apps and to integrate Zello Work within your own app. The server-side API is available to anyone with a Zello Work account.

(Note: Channels SDK and Channels API, with limited functionality, is available for the free app.)
